Application filed July 11,

My invention relates to shoe machineryand more particularly to the so-called edge set: ting machine, designed and used in finishing the top lifts on wood heels, and heels madeof other materials. The objects of my inventionare to speed up production; to minimize production costs; to improve the quality ofv finish to eliminate holding acks inheel. finishing machines; to provide an improved finishing machine designed to pound and rub-so as to literally drive the finish into thepolished surface; to provide a new and novel oscil-- lating iron movement; to provide a new and novel iron embodying a ridged surface either in one piece or in assembled units to provide a new and. novel combination comprising a movable edge iron with an adjustable gauge plate adaptable to set the iron at designated distances and varying angles in re lation to the edge iron; to provide means for exerting an adjustable spring pressure on the heel while the'finish is being applied to the top lift, so as to furnish a firm yetyielding pressure, insuring no injury to theheel surface or heel cover at the points of contact; to provide a pressure means adaptable to travel with the surface of theheel as the top lift is rotated on the edge iron thus eliminating friction, surface fracture and injury to the heel cover or finish; to provide a new and novel combination of an edge iron with a travelling spring pressure :to provide a new and novel combination of an edge iron, a travelling spring pressure and an adjustable guide plate or gauge; to provide quicklyinterchangeable pressure arms; to provide a travelling pressure means adaptable to rest against the surface of a heel in the process of finishing, deriving its horizontal motion from the heel as said heel is rotated, and utilizing a combination spring and foot lever pressure for'vertical motion; to provide a new and novel acjusting means on the pressure lever so as to render it capable of furnishing varying loads and adaptable to heels of various sizes; and to furnish the various other advantages and results made evident from the following specification. V

I accomplish the objects of my invention as shown in theaccompanying drawings, which form a part of this specification, andin which Figure 1 shows a front view of my machine. Figure 2 shows a partial side view of the ma.- chine frame at its top portion, the edge iron and back guide plate. Figure 3 shows the edge iron and pressure arm with a heel, in

Figure 7 shows the'detail of my. W shaped auxiliary pressure arm designed to care for thetravel of the heel corners so as to insure a steadier and more uniform turning of the top lift edge against the finishing iron, to gether with a heel in position thereon,'and a partial front view of the finishing iron. Figure 8 shows, the same parts as; Figure 7 with the heel in a, progressive turning position. Figure 9shows the heel'in a further progressive turning position; .Figure l0-shows the heel in its position at the final finishingstage.

H shows an adjusting collar, encircling the pressure bar F, fitted with a hand screw H for tightening and holding the pressure spring H so as to provide therequired pressure on heels of varying sizes. H shows the connecting member between the pressure, bar F and the foot lever G designed to receive one endof the pressure lever F,

allowing its free play therein and affordin' unrestricted adjustments. I showsmy a justable gauge platel -Since the connecting member H is pivoted to foot lever G a limited swinging movement for horizontal movement of the pressure baris set up as the finishing ironoscillates on the heel, and limited vertical movement is also attainedby the sliding movement of member F during'the operating of my device against the pressure of the spring the two movements which accordingly are transmitted to the pressure bar may be termed traveling since the pressure bar follows to a limited extent the configuration of the heel and is influenced by the oscillating movement of the finishing iron.

Referring againto Figure 2 I shows the pivot on which the gauge plate 'I is mountedso as to allow various angular adjustments, in anyof which ustment'sit is held by the from the finishing iron C is regulated by the threaded shaft J and nuts J and J arm I and "the thumb screw 1*. Distance Referring again to Figure 3, K shows a heel in position-for finishing between the iron G and the pressure arm D. l

Referring again to Figures 7, 8, 9 and 10, K shows the heel in its varying travelling positions,-r'luring the process of finishing.

Referring again to Figure 4, the units C ofthe composite iron are assembled in the holder C so that the high points on their outer or contacting surface G form an arc in proper ratio to' the oscillating movement created by-the eccentric B and arm B .thus 'duringthe arms oscillating movement, in-

suring successive and equal contacts of the respective high points against that portion of the heel being finished. The successive and equal contact of the respective high points is broken by the smaller radius on each side of the high point as the oscillatingmovement progresses, and as the successive units C come into contacting position, pounding and rubbing'as they pass. It will be seen that the pounding effect is created by the depressions or valleys on the surface C of the irons together with the spring force exerted by the pressure bar. The series of finishing units in the iron minimize the breaking of contact between the heel and the iron during the free hand turning of the heel by the operator, duringthe finishing process, thus speeding production and insuring improved results.

Referring again to Figures 7, 8, 9 and 10, it will be recognized that the W shaped form of the arm I.) is designed to facilitate the freehand turning of the heel by the operator during the finishing process. Its use is particularly adaptable in the finishing of large heels. Smaller heels, as shown in Figure 3 do not require the W shaped arm. When smaller heels are to be finished the bar D is swung on bolt D to its downward or inoperative position, and the bar D is swung up to its operative position as shown in Figure 1.

Similar letters of the reference refer to similar parts throughout the various views. While I, have illustrated and described a preferred construction for carrying my invention into effect, this is capable of variation or modification without departing from the spirit of the invention. I therefore do not wish to be limited to the exact details of construction herein set forth but desire to avail viding a corrugated surface adaptable for successive contactswith material on which a finish is to be applied and adjustable and slightly movablemeans for pressing said-ma terial against said iron.

2. In a machine of the kind described, an edge iron formed of separate units adjustable with respect to each other, and each unit hav ing a curved face adapted to provide in assembly a corrugated surface, means for oscil= lating said iron against material on which a finish is to be applied, 'andadjustable means for pressing said material against said iron, said means mounted for limited movement in two directions during the pressing operation.
